Abstract

A contact element having at least one leaf spring 2,3 has a U-shaped contact means 6, the two U-legs 8,9 of which taper towards their ends and can be elastically deformed with respect to each other. This contact element 1 is introduced into a guide groove 22 of a guide rail 13 of a module support structure or the like. The leaf springs 2,3 thereby contact a printed circuit board which can be inserted into the module support structure and the contact means 6, together with guide rail 13, can be clamped in a positioning hole 15 of a module rail 16 of the module support structure to thereby establish electrical contact with the module rail 16. In this manner, the interfering effect of an anodized layer on the module rail 16 is circumvented.
